Link Between Pulmonary Inflammation, Diesel Exhaust, House Dust

Link Between Pulmonary Inflammation, Diesel Exhaust, House Dust

Numerous exposures such as viral infections, indoor as well as outdoor allergens and ambient pollution contribute to the development of asthma in childhood and the persistence of asthma in adulthood. Environmental influences weigh heavily on early lung growth, particularly traffic-related pollution. Children develop asthma and related pulmonary infections at an increased rate when exposed to these pollutants.

Exposure to both HDE and DEP demonstrated increased mucus production and higher airway resistance compared to exposure to only HDE. Pulmonary inflammation was measured by oxidative stress, respiratory physiological features, inflammatory cell recruitment and local CXC chemokine production, or soluble mediators of inflammation.

"The highlight of our study is that you can remove some of the allergen exposure by cleaning, but DEP's are especially hard to avoid in urban environments," explained Professor Jiyoun Kim.
According to Kim, this research also shows a direct link between air pollution and exacerbation of pre-existing pulmonary diseases, like asthma. "We have not reached a medicinal solution yet, but this study reveals that there could be a tangible therapeutic target and that anti-oxidative treatment could be beneficial to asthmatic patients, especially those with increased exposure to air pollutants."
